I personally experienced a part of this problem. I had a coronary procedure for which medicare paid the hospital just over $23,000 when a previous $2,000 test plus consideration of symptoms showed I had virtually no coronary occlusion.
The sequence -
#1. New PCP doc wanted a second coronary calcium scan. My first scan 4 year previous showed enough calcium, the statistical average has some coronary artery disease. Another consideration was to measure rate of calcium buildup change. I have had high cholesterol since before statin drugs existed.
#2. Cardiologist said need to get measure if your heart can get adequate blood - nuclear stress test. (Note - I have never experienced any chest pain and I do exercise regularly on treadmills plus brisk outdoor walks.)
#3. Results the same as 4 year earlier - some indication of occlusion, but no angina. If the exact scans of this test were compared to the earlier one, no differences would have been found.
#4. PCP says in her experience when people get this result, virtually all cardiologists go for an angiogram.
#5. Cardiologist recommends, but significantly does not say “should” or “need” a CT angiogram. This specific test shows results that are consistent with an 60% to 80% occlusion of one artery and significant occlusion in another.
This got my attention! The cardiologist says arterial angiogram – open an artery up, run a wire into the heart and look blood flow of the suspect arteries. The cardiologist does state, all we really know for sure is I have significant amounts of calcium associated with my arteries. That a calcium could be inside on the walls occluding blood flow. It could be on the exterior or the coronary artery. It could even be within the artery wall.
#6. On July 3rd at 5:30am, I am prepped. My procedure is delayed 45 minutes - somebody had just arrived at the ER undergoing a heart attach and opening his arteries was more important than just checking mine out.
8:30am – I am out the door having been told my arteries are great - I have one 10% occlusion and that is abnormally good for an 81 year old male.
The key connections that were not made:
#1. Despite exercise to heart rates at 80% of my “max heart rate” I had never experienced any chest pain. (True I could have ignored discomfort or actually failed to admit pain.)
#2. Both nuclear stress tests showed the exact same result -a minor blood insufficiency and NO CHANGE in the apparent coronary blood flow insufficiency when exercising on the treadmill.
When my PCP and I went through all this history and actual test results, it was clear to both of us, that $23,000 arterial angiogram was a waste of money.
A totally unrelated event lead to an abdominal CT scan and among the radiologist’s notes was an aortic aneurysm. Since this is not close to the size where surgery is needed, my PCP and I will be looking long and hard before surgery is even considered.
